LEB(i)
19 And God said, "No, but Sarah your wife shall bear a son for you, and you shall call his name Isaac. And I will establish my covenant with him as an everlasting covenant to his offspring after him.
20 And as for Ishmael, I have heard you. Behold, I will bless him and I will make him fruitful, and I will multiply him ⌊exceedingly⌋.* He shall father twelve princes, and I will make him a great nation.
21 But my covenant I will establish with Isaac, whom Sarah shall bear to you at this appointed time next year."
